Mernda Retirement Village Road 2 Wall


This project was a big under taking for Stringline due to it value and short time frame. The retaining wall was designed to have a 25Kpa loading so all components were special order even down to the steel and panels.

The upright steel is the largest rolled H beam on the market. All panels were specially fabricated to suit. The mythology for the construction of this retaining wall was unique as we were protecting existing assets located close behind the retaining wall.
